RECORDING DOOR-LOCK.

Specification of Letters Patent.

Patented Dec. 5, 1911.

Application filed October 18, 1907. Serial No. 398,047.

' lation to improvements in door locks.

rmcipal object of this invention is The to provide a lock of this class with permutation devices for controlling the operating mechanism and the designating recording devices.

Another object of this invention is to have the recording devices that are controlled by the clock mechanism independent of said mechanism until an impression is to be taken so that they will have no retarding influence upon the clock mechanism.

lVith these and incidental objects in view the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and apreferred form of embodiment of which is hereinafter specifically described with reference to the drawings which accompany and form part of this specification.

'Of said drawings, Figure 1 represents a front elevation of the lock with the cover removed. Fig. 2 represents a vertical transverse section through Fig. 1. Fig. 3 represents a detail horizontal section of the permutation devices and the type wheel set thereby. Fig. i represents an enlarged detail front elevation of a pair of disks forming a part of the permutation devices. Fig. 5 represents a detail side elevation of the disks shown in Fig. 4:. Fig. 6 represents a detail side elevation of a part of the clock train showing the winding device in section. Fig. 7 represents a detail front elevation of one of the step cams operated by the clock train and its cooperating type wheel, and Fig. 8 represents a detail front elevation of the character printing wheel and the means for setting same.

This invention is chiefly designed for use on doors of commercial establishments, for recording the time of the arrival or departure of the different clerks and also a designating character to identify the several clerks. Permutation devices control the setting of the identifying type carrier while the time. type carriers are controlled by step cams which are driven by clock mechanism. The permutation devices in connection with a key which is inserted in an operatin knob controlv the mechanism so that if the evices have been properly set and the key inserted the knob may be rotated to take an impression from the type carriers upon a record strip which in connection with an inking' ribbon fed forward just before an impression is taken, after which the locking bolt will be thrown or withdrawn, depending upon the direction in which the knob is rotated. The hour step cam controls the operation of an ante-meridian and post meridian type carrier and also a day type carrier which, in connection with a month type wheel that is manually operated, are arranged to record upon the record strip in alinement with the time and identifying type carriers. The permutation devices are so designed as to allow the taking of an impression from the type carriers, but at the same time to prevent the operation of the bolt, as for instance, when it is desired to record the visit of a watchman.

Having described in general terms the operation of the look, a more specific description will now be given.

In the accompanying drawings 1 represents the casing which surrounds the recording devices, and 2 a section of' a door to which it is secured. Within the casing 1 is mounted an ordinary clock train with escapement, see Figs. 2 and 6, of which 3 represents a gear driven by a main spring 4, one end of which is secured to a shaft 5, while its other end is attached to the gear 3. This gear meshes with a pinion 6 which is secured to a shaft 7, and to which is fastened a pinion 8 that meshes with a gear 9 which is mounted upon a shaft 10. This I and minute type carriers, 16 and 17 respectively, are provided with pinions 18 which are arranged to be engaged by vertical spring drawn rack bars 19. Each one of these bars is provided with a foot 20, see Fig. 1, which extends under a projection 21 formed upon a slide 22 which is guided by slot and pin connections 23. The upper end of the slide is provided with a platen24. This slide is provided with two pins 25 and 26 which are arranged to be engaged by a disk eccentrically mounted upon the shank 28 of a door knob 29, see Fig. 2. This knob 29 is normally locked by tumblers 29 and is released by the insertion of a suitable keg, 30. As the-knob 29 is turned the disk 27 cams the slide 22 upwardly, allowing the rack bars 19 also to move upwardly by their springs 31. As the greatest movement of the rack bars 19 is considerably less' than the movement imparted to the slide 22, 'it will be seenthat the said bars and the type carriers 16 and 17 actuated thereby will be at rest when the platen 24 takes an impression from said type carriers.

As the slide 22 is cammed upwardly, a spring pawl 32 attached thereto, engages a ratchet 33 fastened to one end of a sleeve 35 which surrounds a shaft 36 projecting outwardly from the inner portion of the casing 1. To this sleeve is fastened one end of a record strip 37 which is fed over guide pins 37 from a supply roll 37. Apinion 34 is also secured to the sleeve 35 and meshes with a similar pinion 38 mounted loosely upon a stub shaft 38. An absorbent ink roller 39 surrounds the shaft 38 and is attached to the pinion 38. A ribbon 40 passes around the roller 39 and guide pins 4O and between the type carriers and record strip. It will be seen from the above description that at the beginning of the upward movement of the slide 22, the record strip 37 and the ink ribbon 40 will be slightly advanced, andat the end of said movement the platen 24 will take an impression upon the record strip from the type carriers. As the slide 22 returns toward normal position, the pawl 32 will spring over the teeth of the ratchet 33, the latter being held in its advanced position by a pawl 33*. Projecting from the disk 27 is a pin 41, which is arranged to engage with a vertical arm 42 of a bell crank slide 43 just, before the disk 27 forces the platen 24 into contact with the type carriers to take an impression therel'rom.

If the permutation devices hereinafter described have been properly set the pin 41 will move the slide 43 to the right against the tension of its s ring 44. This sidewise movement of the slide 43 will cam a spring drawn slide 46 upwardly by means of the walls of a V shaped notch 45, formed in the horizontal arm of the slide to receive the lower wedge end of the slide 46. The upper end of the slide 46 is provided with a lateral extension 47 which, when the slide is raised, enters notches formed in disks comprisin a part of the permutation devices hereina ter described. The slides 43 and 46 are secured to the casing by suitable slot and pin connections. Projecting from the disk 27 is another pin 50 which is arranged to engage with a slide 51 and force it upward, so as to raise the stud 52 formed thereon out ofengagement with one of the notches 53 formed upon the shank 54 of the bolt 55. The continued rotation of the disk 27 will bring the pin 50 into engagement with one side of a slot 56 formed in the aforesaid shank 54 and draw the bolt 55 out of engagement with its keeper (not shown.) Upon the movement of the disk 27 in the opposite direction the pin 50 will engage the other side of the slot 56 and force the bolt into locking position.

It will be seen from the above description 'in the same direction, thereby camming the platen 24 upward. As the slide 22 moves upwardly the spring 32 carried thereby will engage the ratchet 33 and feed the record strip and ink ribbon forward. Just before the platen takes an impression from the type carriers the pin 41 carried by the disk 27 will engage the vertical arm 42 of the bell crank 43 and slide it to the right in said figure against the tension of its spring 44. The bell crank as it moves toward the right will cam the slide 46 upwardly as described thereby carrying the lateral extension 47 of said slide into the notches of the permutation devices. The continued rotation of the knob will throw the bolt, the lug 52 of the slide 57 then dropping into the notch 53 of the shank 54, thereby locking the bolt from accidental movement. After the taking of an impression and the withdrawal of the bolt the disk 27 will cam the slide 22 carrying the platen 24 downwardly engaging the pin 25 projecting from the slide, which in turn will withdraw the rack bars 19 from contact with the step cams 14 and 15 and hold them in their lowered positions. In the meantime the pin 41 having passed out of engagement with the arm 42 of the bell crank 43, the latter will be drawn back to its normal osition by the spring 44, as will also the sli e 46 by its spring.

The permutation devices comprise a plurality of adjustable dials which must be properly set before the operating knob can e turned far enough to cam the platen into contact with the type carriers or operate the locking bolt. These devices also control the setting of a character type carrier so that when they are properly set and an impression taken, a character identifying the op erator as well as the time will be recorded upon the record strip. Referring now to Figs. 3 and 4, it will be seen that the said devices comprise dials 56 which are secured to the outer ends of sleeves 57 and 58 and shaft 59, the other end of said sleeves and shaft being provided with disks 60 each one of which is e uipped with three deep notches 61 and one s allow notch 62. Ad acent to these disks are disks 63 of the same size which are loosely mounted upon the shaft or sleeves. These disks are provided with one deep and one shallow notch, 64 and 65, similar to the slots 61 and 62 respectively, and are arranged'to be secured to the disks 60 by means of a double tenon 66, which enters mortises 67 and 68 formed in the disks 60 and 63 respectively, as shown in Fig. 5. The objects of the disks 63 is to enable the proprietor to change the combination when desired by simply withdrawing the tenon 66 and rotating the disk 60 sufficiently to bring another one of the slots 61 to register with the slot 64 formed upon the disk 63. When the slots 61 and 64 register, the tenon 66 is inserted into the companion mortises 67 and 68. The casing 1 is provided with an opening 69, see Fig. 1, through which the proprietor may change the combination whenever desired. An arm 70 formed upon the lid 71 normally closes this opening. This lid is secured to the casing by means of a lock 72. A cyclometer may be secured to this lid so as to register the number of times the lid has been removed and in this way enable the proprietor to know if the recording device inclosed within the casing has been tampered with. The shallow recesses 62 and 65 formed upon the said disks are to enable the watchman to record his visits without throwing the bolt in the following manner: He inserts his key 30 in the knob 29 which releases said knob and allows same to be turned. The pin 41 formed upon the disk 27 will engage with the arm 42 of the bell crank 43 and force the same slightly to the right sufiicient to allow the disk 27 to force the platen 24 into engagement with the type wheels. This movement of the bell crank to the right is not sutficient to allow a full turn of the knob 29 because the watchmans combination sets up the reduced recesses 62 and 65 formed on-the plates 60 and 63 respectively, thereby limiting the movement of the slide 46 so. as to prevent the pin tached to the innermost disk 60. 'While only one of the dials 56 operates the type carrier 92, it is to be understood that the other dials 56 will have to be roperly set before an impression can be ta (en.

In order to remove all uncertainty, which may arise on account of the duplicate set of types. carried by the hour type carrier, as to whether the look was operated before or after 12 M., a type segment is provided to record ante-meridian and post-meridian and is controlled by the hour type carrier. This type carrier which is designated by the numeral 16, see Fig. 2, is fastened to one end of a short shaft 73 by means of a spline 74, the other end of said shaft having secured to it a single toothed disk 75 and a disk 76 provided with a cut out portion 77, see Fig. 7. This shaft is mounted in a frame work 73 which is secured to the sides of the casing 1. Mounted upon a shaft 89 and in the same vertical plane as the disk 76, is a disk 78 provided with concave portions 79 arranged to engage with the periphery of the disk 76 and thereby lock the disk 78 and a type segment 80 secured thereto from any accidental movement. This segment 80, at its lower end, carries types A and P representing anti-meridian and post-meridian, and at its upper end is provided with teeth which are arranged to be engaged by the single tooth fcrmed upon the disk 75 and thereby rotate the segment 80 to bring the proper type in position to be recorded. When the platen is cammed upwardly, as previously described, the rack bars 19 will follow the same, thereby rotating the type carriers 16 and 17 until the upper ends of said bars contact with the steps upon the cams 14. and 15. If the time to be recorded is A. M. the single tooth disk 75, which is connected to the hour type carrier 16, will not engage with the teeth of the type segment 80 and consequently the letter A which is normally in printing position will be recorded upon the strip; while if the time to be recorded -P. M. the disk 75 will be rotated far enough to turn the segment so as to bring the letter P into printing position. The duplicate types in the wheel 16 may be heavy and light so as to indicate ante-meridian and post-meridian if desired.

The shaft 89 upon which the disk 78 and the type segment 80 are loosely mounted, has secured to it a type carrier 82 for recording the day of the month. This carrier is rotated automatically by a cam. 84 secured to the hour step cam 14, which engages the upper end of a spring pressed arm 85, the lower end being pivoted to the casing 1. Pivoted to this arm 85 is a pawl 86 which engages a ratchet wheel 87 secured to the type carrier 82. It will be seen from this construction that upon a complete revolution of the cam 84, which occurs once every twenty four hours, the type carrier 82 will be advanced one space. A spring pressed pawl 87 prevents any retrograde movement of said type carrier. As the days of the different months vary it will be necessary to set this printing wheel by hand at the beginning of each month, which is done by means of a pointer 88 fast to one end of the shaft 89. The month printing wheel is set by means of a similar pointer 90 which is secured to a sleeve 91 that surrounds the shaft 89, the other end of said sleeve carrying a month printing whcel 83. These pointers play over a dial 91* which is provided with two circles of numerals, one reading from one to twelve for the months and the other from one to thirty one for the days.

Referring now to Fig. 6, it will be seen that the rewinding shafi 5 is provided with a square head 96 which fits into a recess formed in a barrel 97 of a lock casing 98. This barrel is provided with plunger pins 99 which cooperate with drivers 99 mounted within the casing 98 to prevent any movement of said barrel and consequently the rewinding of the main spring 4 unless the proper key 100, which is carried by the proprietor or some authorized person, has been inserted. By this means prejudiced employees are prevented from putting the clock mechanism out of working ouder by winding the main spring too tight.

Having described the invention in detail a brief description of its operation will now be given and the different parts designated by their reference numerals. After the insertion of the key 30 and the setting of the dials 56 the operating knob 29 will be turned, which through the disk 27 and the pin 26 will cam the slide 22 and the platen 2-l carried thereby upward. As the slide 22 moves upwardly rack bars 19, normally held down against the tension oftheir springs 31 by projection 21 of the slide extending over the feet 20 of the rack bars, will follow said slide until their upper ends contact with the step cams l4 and 15, after which the platen will be forced into contact with the type carriers to take an impression upon the record strip 37 through a inking ribbon 40. Just previous to the taking of an impression the pawl 32 carried by the slide 22 will engage a ratchet 33 and feed the record strip, and through the pinions 34 and 38 also feed the ribbon. In the meantime a pin 50 projecting from the disk 27 will elevate the slide 51 and just after taking the impression will contact with one side of the slot 56 formed in the shank 54 and operate the bolt 55. The continued rotation of the knob will, by the disk 27 engaging the pin 25, lower the slide and thereby withdraw the actuating racks 19 so as to free the clock mechanism of any retarding influence that the actuators would have if driven directly by said mechanism.

In a device of this kind, where it is used to record the arrival and departure of persons, it is very essential that the clock mechanism be as accurate as possible and by having the time recording devices normally independent of the clock mechanism there is less danger of said mechanism going wrong.

By the use of permutation devices for controlling the setting of the special type carrier a greater number of people may operate the lock than if the type carrier was differentially adjusted by the insertion of diiferent shaped keys. Further, with all key locks the clerks may lose their keys or leave without turning them in and, in this case, the proprietor does not know who might enter his store after it is. closed.

On account of the hold one may secure in the knob, the operation of the bolt and the impression devices is made much easier than if they were operated by keys as is the case in some machines on the market.

\Vhile the form of device here shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not desired to confine the invention to the one form of embodiment here disclosed, for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
